Of all the Finnforest albums, 1979's Demonnights is the Jussi Tegelman album. The band's previous records were mostly composed by his brother Pekka Tegelman but now the situation was quite the opposite: Pekka had only one composition, Jarmo Savolainen (a new member of the group) had one and the rest were composed by Jussi. Pekka had in fact left the group prior to Demonnights to pursue other musical projects, but played on the album nevertheless. Despite Pekka's presence, at the time of their final album's release Finnforest was mainly Jussi Tegelman's project.
Right from the start when the melodic, upbeat "The First and the Happy Schoolday" kicks in, you can sense that the album is very different in comparison to Finnforest's previous efforts. First of all the lineup is bigger: Jussi Tegelman (drums, percussion, vocals), Pekka Tegelman (electric & acoustic guitar), Jari "Jarkka" Rissanen (electric guitar), Juhani Aaltonen (tenor & soprano saxophone, flute, bass flute), Tuomo Helin (electric bass), Ilkka "Petri" Pettersson (vocals) and Jarmo Savolainen (piano, electric piano, Arp Odyssey synthesizer). "It's not difficult to hear from the material that Weather Report was the main musical influence," Jussi says now of Demonnights.
This was their first album not recorded at Marcus Music Studios in Stockholm. With the financial help of their mid-70's hit records, Love Records had built its own studio and that's where Demonnights was recorded captured. Måns Grundstroem – who produced the previous Finnforest albums – was the recording engineer and Jussi was in addition to being the main composer, also the album producer. Svart Records' reissue of Demonnights comes complete with unseen photos plus new, extensive liner notes by Arttu Seppänen.
